Summary

Ephemerisle is a unique annual gathering held in July on the Sacramento-San Joaquin Delta, where participants build a floating city without a central organization or formal rules. Everyone is encouraged to contribute, and the event has taken place since 2009, originally founded by the Seasteading Institute to explore autonomous societies on water. Each year, attendees live on houseboats, forming independent ‘islands’ with their guidelines. The 2025 event is scheduled for July 21-27 at Mandeville Tip. The gathering fosters a community that values seasteading, art, learning, and connection among diverse individuals. The shared motto - ‘No Dying’ - underlines the emphasis on safety and cooperation. Ephemerisle continues to evolve, remaining a platform for creativity and collaboration on the water.

Floating Cities and Autonomous Communities Ephemerisle promotes the idea of living in floating communities without centralized control. Shift from traditional land-based living to innovative water-based lifestyles. In a decade, we might see more established floating cities with unique governance structures. Rising sea levels and urbanization may push people towards alternative living solutions. 4
Community-Driven Events Ephemerisle relies on participant contributions instead of formal organization. Transition from organized, ticketed events to more spontaneous, participatory gatherings. Future events may see more decentralized and peer-driven social experiments. Desire for authentic connections and shared experiences beyond commercial constraints. 5
Integration of Art with Environment Art plays a significant role in the expression of the Ephemerisle community on water. Evolution from land-based art towards a fusion of creativity and aquatic environments. Art festivals on water may become mainstream, reshaping artistic expression. Increasing interest in experiential art that interacts with nature and community. 3
Skill-Sharing Culture Attendees share and gain boating and nautical skills in a community context. From formal education to informal peer-to-peer learning on practical skills. Learning platforms may increasingly favor experiential skills-sharing over traditional education. The need for practical skills in changing environments encourages collaboration and sharing. 4
Autonomous Islands Concept Event governance is based on independent groups forming their own rules. Shift from centralized authority to decentralized, self-governing communities. Other neighborhoods or events may adopt this model for more local autonomy and freedom. The growing desire for autonomy and self-determination in societal structures. 5
